Abstract
A line of new instruments is described which use light scattering to measure various parameters of particulate distributions. Employing laser illumination of a flowing stream of particles, a Fraunhofer diffraction pattern is produced and processed with optical and electronic means. Various parameters of the particle size distribution are measured, including a thirteen segment histogram of the volume size distribution. The measurement is rapid and continuous. Technical background and instrumentation is discussed. Many applications have been made, and this paper includes three examples relating to industrial quality control involving particles.
